Answer 1

3.105 x 10 ^-6 because you are moving the decimal point back the exponent becomes negative

Answer 2

`3.015*10^(-7)`.

Explanation:

Given : 0.0000003105 .

To find : Write in scientific notation.

Solution : We have given 0.0000003105.

Steps to write in scientific notation :

Step 1 : If a number has n digit we move decimal point ( n-1) place to left

and to balance , multiply by
`10^(n-1)` .

We can write 0.0000003105 as
`(3105)/(10000000000)`.

Or
`(3105)/(10^(10))`.

`(3.015*10^(3))/(10^(10) )`.

`(3.015)/(10^(7) )`.

`3.015*10^(-7)`.

Therefore,
`3.015*10^(-7)`.
